CALI-US CORN REMOVER.

Application filed August 29, 1919.

T 0 all whom it may concern:

Be it known that I, GEORGE Gmrnns, a citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Callus and Corn Removers, of which the following is a specification.

My invention relates to a cutter or plane for shaving callus or corns from feet or hands or superfluous hairs growing in the almost inaccessible parts of the body.

It consists essentially of an adjustable guard and two clamping or holding plates between which a thin and pliable razor steel cutting blade is rigidly clamped or secured with proper exposure of the cutting edge.

In order that the cutting edge may operate as a plane it is caused to project beyond the edges of the clamping plates and the guard is adjustable by means of a stop for the particular use to which the instrument is to be put.

The first stop is caused by a T pinned to upper surface at rear of guard, allowing the guard to project beyond the cutting edge of blade to give required cutting surface for trimming corns or removing superfluous hairs.

The second or maximum stop is made by sliding guard full distance allowed by slots in guard itself; in making this stop the guard is lowered 01' protuberances in the guard. itself as they pass over the clamping plate after said protuberances have passed the depressions in the lower clamping plate and engage the level surface of the clamping late. p The blade used is preferably of oblong contour with bilateral cutting edges on the long sides and sharp and dangerous corners are eliminated by chamfering them at an angle ofabout 80 to the longitudinal facilitating application of the blade between clamping plates; until engaged the blade is then inserted and stopped by lugs on upper clamping plate.

The main object of the invention, that of providing a perfect cutting surface, is achieved by means of laterally flexing the blade. This is done by a cam working on the handle-bar sliding the guard and clamp ing plates, by means of slots, back and forth over bar at end nearer handle; the other end being pinned in place. Operation of the cam is expedited by fixing a tractor or en- Specification of Letters Patent. -Patented June 28, 1921.

gaging surface to the opposite end of the cam lever; the tractor engages the clamping plates at the proper angle and lifts them to their required arc.

These and other objects will in part be obvious and will in part be hereinafter more fully described. l In the drawings which show by way of illustration one embodiment of the invention, F igure I. is a. front View showing a safety callus and corn removing device embodylng my improvements.

Fig. II.'is a top viewof the same.

Fig. III. is a view of the razor blade or cutting edge intended to be usedin conjunction with same.

In carrying out the invention I have provided a cutting edge of fine razor steel in the shape of a double edged blade, as in Fig. III, held securely in place by a flexed frame with the necessary guard and clamping plates of spring steel operated by stops, levers, etc., as hereinafter more particularly described.

In Fig. I, the instrument is shown flexed, ready for operation. First before flexing, as indicated by 15 showing appearance in dotted lines, the guard 9 is drawn back from the cutting edge as far as the slots 24 permit. This eliminates interference and allows the blade or cutting edge to be inserted between the clamping plates 7 and 8 and is forced back until engaged by lugs 2323 in clamping plate 7. Thestop 12 must be turned on pivot 13 to posltion shown in Fig. 2, whereby it engages the clamping plates 7 and 8 and causes the guard 9 to stop at the position required for cutting corns or removing superfluous hair. The instrument is then flexed into operating semblance by drawing the cam lever 2 toward the bar 1, until on account of its being thrown from balance it automatically locks itself. Meanwhile the cam has forced the tractor 3 to engage the clamping plates and guard and raise them to the required are which facilitates cutting or shaving. In flexing the instrument the guard and clamping plates are moved back and forth over the bar 1 at their end nearer the handle, the opposite end being secured against moving by pins 1114.

To arrange the instrument for operation of removing callus, it is necessary to unlock the cam 2 and open it to position indicated by 4. This involves unflexing, or V TWhen the guard 9 is moved thus fully forward the protuberances 21-21 in guard 9 disengage from the apertures 2020 in the underside of clamping plate 8 causing the guard 9 to be lowered farther from the cutting edge and allowing the blade to cut deeper into the hardened flesh. These protuberances 21-21 and apertures -20 engage or mesh when the instrument is set at the first stop thus allowing the guard to comefin closer contact with the cutting edge.

18 is an escape slot in guard 9, and 19 shows its position when guard is advanced to second stop." p

The lugs 23- 23 inthe clamping plate 7 would interfere with the free movement of the guard 9 and the crimps or depressions 22 22 have been provided in guard 9 to prevent an engagement of these lugs with the guard.

It will also be obvious that minor changes in the details of construction and arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.

I claim- As an improved article of manufacture a safety, adjustable cutter comprising a base bar, a guard and two clamping plates operated by a cam lever and a blade held frictionally between thejclz'imping plates with its cutting edge projecting beyond the l'ongitudinal edges of the clamping plates and guard;
